What are the different types of aircraft corrosion?

What are the different types of aircraft corrosion?

Types of corrosion normally found on aircraft include:

• Uniform surface attack.
• Intergranular corrosion.
• Stress corrosion.
• Crevice or deposit corrosion.
• Filiform corrosion.

What is the most common type of corrosion on aircraft?

Surface corrosion
Surface corrosion: The most common type of aircraft corrosion, surface corrosion occurs when metal on the surface of an aircraft oxidizes, such as when paint wears away.

How many types of corrosion are there in aviation?

There are three main types of crevice corrosion in aircraft: metal ion, oxygen, and active-passive concentration cells.

What is the most corrosion prone metal used on aircraft?

Aluminum
Aluminum and low-alloy steels are the two groups of airplane materials most susceptible to corrosion. Clad aluminum sheet and plate are used where weight and function permit, such as for fuselage skins. Corrosion-resistant aluminum alloys and tempers are used to increase resistance to exfoliation corrosion and SCC.

What is Level 3 corrosion?

Note on Corrosion Levels Level 3 Corrosion is damage found during the first or subsequent inspection(s) which is determined by the operator to be a potential airworthiness concern requiring expeditious action.

What is level1 corrosion?

(1) Level 1 Corrosion is damage occurring between successive inspections that is local. and can be reworked/blended-out within allowable limits as defmed by the manufacturer in a structural repair manual (SRM), service bulletin, etc.

What is Cpcp in aviation?

What is the CPCP? The Corrosion Protection and Control Program is a systematic approach for controlling corrosion in the airplane’s primary structure. The objective of a CPCP is to limit the material loss due to corrosion to a level necessary to maintain airworthiness.

What are different types of corrosion of metals?

As corrosion most often occurs in aqueous environments, we now explore the different types of degradation a metal can experience in such conditions:

• Uniform Corrosion.
• Pitting Corrosion.
• Crevice Corrosion.
• Intergranular Corrosion.
• Stress Corrosion Cracking (SCC)
• Galvanic Corrosion.
• Conclusion.

What are 3 main types of corrosion?

CORROSION TYPES And Prevention

• Uniform Corrosion. Uniform corrosion is considered an even attack across the surface of a material and is the most common type of corrosion.
• Pitting Corrosion.
• Crevice Corrosion.
• Intergranular Corrosion.
• Stress Corrosion Cracking (SCC)
• Galvanic Corrosion.
• Conclusion.
